Dr Raghav said: “In June 2019, the patient had increasing symptoms of shortness of breath and fatigue, and scans showed disease progression in both the lungs and the liver.

“Patient was then switched to 5-fluorouracil, leucovorin, irinotecan and cetuximab and received this treatment until August 2020 with stable disease as the best response.

“In August 2020, the patient had progressive disease and was given regorafenib.”

He added: “Interestingly, it’s strange that the patient developed this disease in a rather short interval from the last colonoscopy, which was completely negative.”
